Temperature Transmitter

Temperature transmitters receive signals from RTD or thermocouple sensors and convert the measured temperature into standardized electrical signal for remote monitoring and control. SUPMEA models such as the SUP-ST500 accept RTD, thermocouple and linear-resistance inputs and provide a 4–20 mA two-wire output. 

The transmitter conditions and linearizes the sensor signal, applies cold-junction compensation for thermocouple inputs, and provides configurable input ranges for different sensor types. Selected versions also provide electrical isolation between input and output to improve signal integrity in industrial environments. The standardized output can be sent over long cable runs to PLC, DCS, recorders or indicators, where it is used for display, alarming, data logging and process control.
